How to Set dynamic title depend on drill down/up?

[kenrisen]

Hi all Cognos Gurus..

I have a report with drill down/drill up function and a title. The title have to change dyanamic everytime I drill down/drill up the report. I have built using a data linking but I found an issue when I drill down until the last element and drill up, the title will be wrong.

How to solve this problem?
Is it a bug in cognos 10.1?

FYI..
I tried with cognos package sample (Go Data Warehouse Analysis).

report studio spec
